Movement of phase boundaries of metals subjected to surface periodic energy pulses

The heat phenomena including heating, melting, evaporation, cooling, and solidification are analyzed by means of mathematical modeling. Velocities and positions of phase boundaries (both evaporation and melting) are determined for different conditions of pulse-periodic energy flow irradiation of metallic materials. Heat process dynamics, determined by the shape of the single energy pulse, by the energy input per oscillation period, and by the average energy density flow, are discussed.
